From c283a711c850efaab4fe3bca5ef7200eb854bba1 Mon Sep 17 00:00:00 2001 From: Tobias Burnus Date: Fri, 6 Nov 2020 08:26:51 +0100 Subject: [PATCH] Fortran: Fix type-decl for PDT / wrong-code pdt_14.f03 issue [PR97652] Parameterized derived types are handled in a special way and start with 'Pdt'. If the 'P' is not uppercase, gfc_get_derived_type (which calls gfc_get_module_backend_decl) does not find the existing declaration and builds a new type. The middle end then sees those types as being different and nonalising, creating an endless loop for pdt_14.f03. gcc/fortran/ChangeLog: PR fortran/97652 * module.c (mio_symbol): Fix symbol name for pdt_type. --- gcc/fortran/module.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/gcc/fortran/module.c b/gcc/fortran/module.c index 33e7df7..4c6ff22 100644 --- a/gcc/fortran/module.c +++ b/gcc/fortran/module.c @@ -4549,6 +4549,9 @@ mio_symbol (gfc_symbol *sym) mio_symbol_attribute (&sym->attr); + if (sym->attr.pdt_type) + sym->name = gfc_dt_upper_string (sym->name); + /* Note that components are always saved, even if they are supposed to be private.
